This is a high current cell with not that much capacity.











The two cells tracks nicely and they can deliver 30A.

I had to skip the temperature curves, I forgot to replace the battery (It last about a year).















Conclusion

The battery is a bit low in capacity, but it can deliver a lot of current.

Interesting discharge curve shape, remembers me to that of Vapcell INR18650 2000mAh (Black) and those of Samsung INR21700-30T 3000mAh (Gray) and its Vapcell INR21700 3100mAh (Purple) rewrap.

One of the 30A discharge curves is trimmed off. Maybe the cell overheated?

Cheers :-)

It lost contact, maybe due to overheating.

At the same time, it’s quite normal is the rewrap of the cell Samsung INR18650-24S (2400mAh typical and 30 amps continuous real), the best cell 18650 in 30A continuous of all time nobody did better than this cell until then in this type of cell 18650 (30A continuous).
